David Lowry’s Blog 29th June 2018, Article I of the NPT starts with the following commitment on Russia, the US
and UK: “Each nuclear-weapon State Party to the Treaty undertakes not to
transfer to any recipient whatsoever nuclear weapons or other nuclear
explosive devices or control over such weapons or explosive devices
directly, or indirectly”

Extraordinarily, just two days earlier in
Washington, the US hosted a bilateral meeting with the UK to celebrate the
60th anniversary – from July 3, 1958 – of a hugely significant nuclear
defence agreement (commonly called the US–UK Mutual Defense
Agreement,(MDA) with defence spelled with an ‘s’ even in the official
UK version, hinting at the origin of its drafting).http://drdavidlowry.blogspot.com/2018/06/naked-nuclear-hypocrisy.html
